Use the following guidelines to troubleshoot your iFIX connections if you experience difficulty accessing process data:
If you have Proficy Portal and iFIX running on the same computer, do not shut down iFIX when a request for data has been sent. If you shut down iFIX, you cannot restart it until you stop and restart the Proficy Portal server.
NOTE: When you run iFIX on a remote computer, you can start and stop iFIX as needed.
Make sure you enable dynamic connections in the iFIX System Configuration Utility (SCU). To enable this option:
From the Configure menu, select Network . The Network Configuration dialog box appears.
Select the Dynamic Connections check box to enable it.
Verify that the iFIX node you are communicating with has SCADA and network support enabled. If it does not, enable this support with the SCU.
Verify that your iFIX node has a hardware key installed. This key is required for iFIX to run longer than two hours at a time.
